- Commodity name: GGJ low voltage intelligent compensation device
Because this device can effectively improve the power factor of the electrical load, reduce line losses, and improve the actual load capacity of the transformer, it has significant energy-saving effects.
Overview
Because this device can effectively improve the power factor of the electrical load, reduce line losses, and improve the actual load capacity of the transformer, it has significant energy-saving effects. At the same time, using specific reactors in the system can also effectively prevent harmonic amplification and effectively Absorb most of the harmonic current, so that the total harmonic voltage distortion rate limit and the harmonic current content limit of each order comply with national standards, achieving the purpose of harmonic control. If an ordinary contactor is used to switch the capacitor bank, it will bring large surge current, slow compensation time, high maintenance costs and short service life. Therefore, we recommend that users give priority to the following occasions Consider using dynamic reactive power compensation devices in low-voltage power grids such as substations of industrial and mining enterprises, production workshops and civil buildings. It is especially suitable for power transmission and distribution systems where the load changes frequently and the reactive power is unstable.
This product complies with standards such as GB/15576-2008 "Low Voltage Complete Sets of Reactive Power Compensation Equipment" and IEC60439 "Low Voltage Complete Sets of Switchgear and Control Equipment".Model meaning

• Change voltage quality and improve power supply reliability.Scope of application
GGJ capacitor cabinet is suitable for all kinds of humid and dusty workshops. It is suitable for factories and mines such as textile, metallurgy, chemical industry, mining, machinery, etc., as a three-phase three-wire, four-wire or five-wire low-voltage distribution system with AC 50Hz, rated voltage 380V or 660V, and rated current up to 630A, for power and lighting distribution. At the same time, it can also be used as a partial control in a low-voltage control system.Functions and features
• It is controlled by an intelligent controller, with complete functions, reliable performance and automatic compensation mode; it can increase the power factor to above 0.9;
• It can display the power factor of the power grid in real time, with a display range of: lagging (0.00-0.99), leading 0.00-0.99);
• It has a variety of comprehensive protection functions such as overvoltage, over-harmonic, over-compensation, system failure, phase loss, overload, etc.;
• It can memorize the set parameters, and the parameters will not be lost after the system power outage. After the power grid returns to normal, it will automatically enter the operating state without the need for personnel on duty;
• It can adopt phase compensation or mixed compensation according to the load balance of the power grid;
• It has strong anti-interference ability and can resist the 2000V interference pulse directly input from the power grid, which is higher than the national professional standard.Distribution network detection function
• Real-time measurement and hourly recording of three-phase voltage, current, frequency, active power, reactive power, power factor, active electricity, reactive electricity on the low-voltage side of the transformer; total voltage and current distortion rate and 2-25 harmonic content;
• With RS-232 and RS-485 interfaces, it can record data on a handheld computer, and can also realize wireless meter reading, device testing, parameter setting and real-time measurement data and recorded data reading through remote communication functions;
